Re: [JAVA3D] Rotation Matrix

[Renoir Sewjee]

If you are able to create the geometry of the objects yourself then you could use 1 geometry array for all of the objects. In the case of 200 cubes:      Use a QuadArray with 200*6*4 coordinates (numCubes*facesPerCube*coordinatesPerFace) .      Use Transform3D to perform the rotations and translations on the vertices of the cube before you put them into the QuadArray.      If you plan on changing the rotations and translations on the cube frequently then use By-Ref geometry. Hope this helps, Renoir Original message   .    .    . I don�t really need to move the objects actually I�m just creating a fixed object (with orbitbehavior) which is comprised of say 200 smaller objects (eg Cube) To position each of the Cubes which make up the overall object I am putting each within a TransformGroup and using the translation method. That gives me 200 TransformGroups.  If I nest them in another transform group for rotation that gives me 400 total transformGroups� seems a tad excessive and I�m sure it�ll hit performance. Is there any other (more efficient/faster) way I can do this without using hundreds of transformGroups??   -- Renoir Sewjee Software Engineer ISS International (Welkom) Tel: +27 (0)57 912 2702 Fax: +27 (0)57 912 2652 --   =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
